Floquil and the related acrylic PollyScale paint lines were for many modelers the go-to paints for model railroading. Unfortunately, Testors discontinued these paints in 2013.
The hobby has good post-Floquil/PollyScale alternatives and this book maps those replacement paints back to familiar Floquil/PollyScale color equivalents. As an added bonus, this book includes several chapters loaded with tips and tricks to help you make an easy transition in a post-Floquil world to painting with state-of-the-art water-based acrylics.
